5 Chapter 1 Introduction 1.1 About the WAN Processor 6800 The WAN Processor 6800 is a Network 9000 Type 1 module. You can install the module into any chassis slot. However, the module requires an adaptor card for installation into any slot other than Slot 1. The Xyplex Hardware Type for the module is 81. A WAN Processor 6800 connects Ethernet/802.3 Local Area Networks (LANs), and forwards packets between them. You connect the 6800 module to one or more partner bridges or routers over a WAN link, and to Ethernet Segment A in the Network 9000 chassis. In discussions of bridging and routing operations, the WAN link is referred to as link W1 and the LAN link to Segment A is referred to as link E1. A WAN Processor 6800 functions as a self-loading partner to any of the following Xyplex Bridges and Routers, or to another 6800 module: MX-6510 Remote Bridge card MX-6710 Remote Router card MX-6020 Remote Bridge unit MX-6220 Remote Router unit Network 9000 WAN Processor 401 WAN Processor 6800 modules provide the following routing and bridging services: Routing WAN Processors are designed to route packets of these network types 1 : Internet (IP) Novell IPX DECnet Phase IV When you turn on (enable) IP, IPX, or DECnet Phase IV routing at a 6800, the 6800 builds tables of paths to accessible IP, Novell Netware, or DECnet IV networks. When forwarding packets to these networks, the 6800 uses a routing process to choose the least cost (preferred) path. 1 For information concerning support for additional network types, such as Appletalk, contact your Xyplex sales representative

6 Introduction Bridging modules can use a bridging process to pass packets of communication protocols other than IP, IPX, and DECnet from one physical network to another 2. When you enable bridging at a 6800 module, the bridging process transparently links remote LAN segments, to effectively form a single extended network. Unlike the routing process, the bridging process cannot always choose a preferred path to a destination. However, the bridging process enables the 6800 module to forward protocols that are not routable, such as the DEC Local Area Transport (LAT) Routing Features Some of the key routing features of the 6800 module include: Support for IP routing, including - Support for Open Shortest Path First (OSPF) as an Interior Gateway Protocol (IGP) 3 - Support for the Routing Information Protocol (RIP) as an IGP 4 - Support for the Exterior Gateway Protocol (EGP) 5 - Support for Route Import and Export filters - Support for IP Traffic filters - Support for User Datagram Protocol (UDP) Broadcast routing - Support for IP protocol prioritization - Support for the Promiscuous (Proxy) Address Resolution Protocol (Proxy ARP) Reverse Address Resolution Protocol (RARP) server capability Support for Novell IPX routing, including: - Support for NetBIOS forwarding - Support for Router Information Protocol (RIP) broadcasting - Support for IPX protocol prioritization - Support for Service Advertisement Protocol (SAP) broadcasting Support for DECnet Phase IV routing, including: - Support for DECnet Import and Export filters, and traffic filters - Support for Level 1 and Level 2 routing - Support for DECnet protocol prioritization 2 If IP, IPX, or DECnet routing is turned off (disabled), the 6800 will use the bridging process to handle packets of these protocols, too Bridge/Routers support OSPF, Version 2, as defined in IETF Request for Comment (RFC) Bridge/Routers support RIP, as described by RFC Bridge/Routers support EGP, as defined by RFC

7 Introduction Using the 6800 as a Remote Bridge If you want the 6800 to perform bridging -- but not routing -- you enable bridging but do not enable IP, IPX, or DECnet Phase IV routing. Following are some of the key features of the bridging software. (These features are provided concurrently with the routing functions when IP, IPX, or DECnet IV routing is enabled.) Support for the IEEE 802.1D/draft 9 Spanning Tree Algorithm and Protocol (STP). Support for filtering and forwarding of all Ethernet protocol types, including: - Non-routable DEC protocols such as LAT and MOP - Xyplex proprietary protocols The 6800 can filter packets based on source address, destination address, and/or Ethernet/802.3 protocol type. It can also filter packets by searching for a specific byte pattern at a specific location. Fully Distributed Redundant Bridging (FDRB). Xyplex Bridge/Routers provide a feature called Interactive Protocol Optimization (IPO ), which can reduce congestion on WAN links that are used for bridging. IPO provides these functions: - Protocol prioritization - Throughput enhancement WAN Connectivity WAN Processor 6800 modules support: The Point-to-Point Protocol (PPP), and the Xyplex proprietary WAN protocol (XCP) 6. Connections to multi-vendor Frame Relay networks. Refer to the Remote Bridge/Router Administrator's Guide for background information about WAN connectivity Bridge/Routers support PPP, as defined by the Internet Requests for Comment (RFCs) 1171, 1172 (Initial Configuration Options for IP), and 1220 (Extensions for Bridging)

8 Introduction SNMP Support WAN Processor 6800 modules accept Simple Network Management Protocol (SNMP) SET, GET, and GET_NEXT instructions, and generate SNMP Trap messages. Refer to the Remote Bridge/Router Administrator's Guide for background information about SNMP support Other 6800 Features Other features of the 6800 Bridge/Router include: A memory card slot. The 6800 module can load its operating software from an optional flash memory card. Flash memory cards are readable/writeable and can be upgraded to a newer software version, and load/store operational parameters Additionally, a 6800 can load software and parameters from a flash memory card to other bridge/router units. Also, if the appropriate software image has been installed on the flash memory card, the 6800 can load other Xyplex unit types (e.g., repeaters). Refer to the Software Installation Guide for Xyplex Loaders for background information about this option. Can obtain software from network load servers over a WAN or LAN link. 7 Five megabytes of memory. Choice of V.35, RS-423, RS-232, RS-422, EIA-530, or X.21 WAN link interface. Allows user interface access via local serial port (MGMT port), or from remote terminals through a network-accessible console port, via the DEC Remote Console Protocol TM (RCP) or TCP/IP Telnet. 7 A 6800 cannot load bridge/router software over a WAN link that has been assigned the Frame Relay or PPP Link Protocol

9 Introduction 1.2 WAN Ports (On the WAN I/O Module) The 6800 module provides a WAN port, to which you connect a communication device that supports one of the following interfaces. The WAN interface type is determined by the WAN I/O module that you install into the rear of the chassis. RS Used for low speed connections. Typically, you use an RS-423 interface for connections through low speed synchronous modems; for example, a modem operating at a speed under 19.2 Kbps. V Used with higher speed connections; typically used for 56 Kbps leased-line service, or a 64 Kbps link. The V.35 interface can support synchronous line speeds up to Mbps. RS Used for low speed connections. Uses same physical connector as RS-423, but has different electrical interface, and supports shorter links than RS-423. RS Typically used for high speed connections, such as subchannels of a T1 link. The RS-422 interface can support synchronous line speeds up to Mbps. EIA Typically used for high-speed connections; this interface type is similar to RS-422, but uses a different connector. The EIA-530 interface can support synchronous line speeds up to Mbps. X An International standard that supports synchronous line speeds up to Mbps. Refer to Chapter 3 for specific cabling information. 1.3 The MGMT Port and Console Port A WAN I/O module provides a MGMT port (Port 1), to which you can connect a terminal, personal computer, or other asynchronous ASCII serial device. The MGMT port provides local access to the bridge/router user interface. A serial cable and RJ-45-to-DB-25 adaptor are shipped with each Network 9000 chassis. Chapter 3 describes other serial cabling options. The 6800 module supports connections to the user interface from remote workstations, through the DEC Remote Console Protocol and TCP/IP Telnet. The 6800 module s console port (Port 0) is a logical port, which provides remote access to the bridge/router user interface from any network device that supports RCP or Telnet. For example, from a Xyplex terminal server running TCP/IP-LAT software, you can access the console port by issuing the TELNET CONSOLE command. Additionally, you can use the NETWORK CONSOLE command to access the 6800 console port from another Xyplex Bridge/Router or Network 9000 Repeater. The NETWORK CONSOLE command is described in the Remote Bridge/Router Administrator's Guide

10 Introduction Making Outbound Connections from the MGMT/Console Port At an MX-6800 Remote Bridge/Router, you can use the NETWORK CONSOLE, TELNET, and TELNET CONSOLE commands to make outbound connections. These commands are described in the Remote Bridge/Router Administrator's Guide. 1.4 Product Prerequisites A 6800 WAN Processor requires Xyplex Bridge/Router software, Version 3.0 or greater (image name RR1.SYS). The 6800 is self-loading; it is initially configured to load its software from a memory card, if one is inserted in its memory card slot. If a memory card is not present, the 6800 will broadcast requests for software from a network host called a load server, which can be: A Xyplex MAXserver Manager (MAXMAN) card Another 6800 or a Network 9000 processor module that is equipped with a flash memory card, which contains the software image "RR1.SYS" A VAX/VMS host system, from which the 6800 can load via the DEC Maintenance Operations Protocol (MOP) A UNIX host system running: - Bootstrap protocol (BOOTP) and Trivial File Transfer Protocol (TFTP), or: - Reverse Address Resolution Protocol (RARP) and TFTP, or - Trivial File Transfer Protocol (for "Directed" TFTP) The load server transmits a software image to the 6800, over the network, whenever the module is powered on or re-initialized. By default, the 6800 requests software from each type of load server, until a server responds with a software load offer. If you need to install software on a network load server, refer to the Software Installation Guide for the type of load server you plan to use. You can configure a 6800 to load software from its flash memory card to other Xyplex units. The Software Installation Guide for Xyplex loaders explains how to configure Xyplex units with flash memory cards to do this

11 Introduction Storing and Loading Operational Parameters Operational parameters affect the operation of the software after it has been loaded. They are modified whenever you issue a DEFINE command. For example, if you issue the DEFINE INTERNET ADDRESS command, the 6800 will update its operational parameter database. The 6800 is initially configured to store its operational parameters locally on a flash memory card, if one is inserted in its memory card slot, and remotely at any properly configured parameter servers. A parameter server can be a MAXserver Manager card (MAXman), another 6800, or a Network 9000 processor module that is equipped with a flash memory card. The parameter server can also be a VAX/VMS or UNIX host system. For information about parameter service through a VAX/VMS or UNIX system, refer to the Software Installation Guide for the appropriate host system. You can configure a 6800 to load parameters for other Xyplex units. The Software Installation Guide for Xyplex Loaders explains how to configure Xyplex units with flash memory cards to do this

15 Chapter 2 Installation Notes 2.1 Prepare for the Installation Before you begin the 6800 installation, you must have completed the Network 9000 chassis installation. If you have not done so, refer to Installing the Network 9000 Intra-Networking Hub. Make sure that you have the following items: Memory card, or software at a load server -- The 6800 module can load software locally from a memory card, or remotely from a network load server. If you plan to use a load server, make sure that the Xyplex Bridge/Router software, V3.0, has been installed at the load server (image name RR1.SYS"). Follow the installation instructions in the Software Installation Guide provided with your software kit. Refer to the Kit Information Sheet provided with the kit for software image names. Also, if the 6800 module will be loading from a network load host, a network parameter server must be available to load and store the module's operational parameters. Parameter storage is described in Section 1.4. Terminal or Workstation/PC -- If you plan to configure the Xyplex Bridge/Router software, you will need a terminal or workstation/pc with terminal emulation to access the bridge/router user interface. Tools -- You will need a small phillips-head screwdriver to secure the modules into the Network 9000 chassis

16 Installation Notes 2.2 Basic Installation Procedure The basic procedure for installing a 6800 module is as follows: 1. Unpack the 6800 module and WAN I/O module. Check the shipping carton contents against the packing list, and inspect for possible damage during shipment. 2. Install the modules in the Network 9000 chassis, following the basic instructions in Installing the Network 9000 Chassis and Installing the MAXserver-to-Network 9000 Adapter Card. Install the WAN I/O module in the slot directly behind the 6800 module. Modules must be securely seated to ensure proper operation. Make sure that the two front panel and two rear panel screws are completely tightened. 3. Complete the Configuration Worksheets that are included with the 6800 module. 4. If the 6800 module is equipped with a memory card, insert the memory card into the card slot on the module's front panel. The memory card is sensitive to static electricity. You should take normal precautions to avoid damaging the data on the card. For example, you can discharge static from your body by touching the side of the chassis before handling the memory card. Section 2.4 describes the activity of the 6800 module's front panel lights during the software loading process. If you are installing a 6800 module that is equipped with a flash memory card, as well as other 6800 modules that are not, install the module with the flash memory card first. That module can then serve as a load server for the other bridge/router modules. 5. (Optional) Initialize the terminal you will use to access the bridge/router user interface, following the instructions in Section 2.5. Terminal cable connections are described in Chapter Run the Bridge/Router Configuration Script to configure basic bridging and routing settings, using the Configuration Worksheets as guidelines. (You are prompted to start the script when you power up the 6800 module for the first time.) 7. Connect cables to the WAN I/O module ports, following the instructions in Chapter

17 Installation Notes 2.3 Loading Software/Parameters from a Network Host (Optional) Refer to this section if you plan to load software from a network load server, rather than from a memory card or other Network 9000 module. A 6800 module cannot load over a WAN link that has been configured for PPP or Frame Relay. A 6800 module module can load software from a network host over its LAN link or WAN link. When you configure a network host to load a 6800 module, you must identify the link(s) that the module uses to load its software with an Internet address or Ethernet address. You use the 6800 module's base Ethernet address to determine the link Ethernet addresses. Determining the Base Ethernet Address To determine the 6800 module's base Ethernet address, look for a label on the Network 9000 chassis that indicates the Ethernet address of the chassis. Add the slot number of the 6800 module to the last digit of the chassis Ethernet address. For example, if the chassis Ethernet address is C0, the address of a module in Slot 2 is C2. Determining the Link Ethernet Addresses You determine the LAN link (E1) Ethernet address by changing the leftmost digit of the fourth byte of the base Ethernet address from 0 to 1. You derive the WAN link (W1) address by changing this digit from 0 to 2. For example, if the base Ethernet address is D5-76, the Ethernet address of the LAN link is D5-76; the Ethernet address of the WAN link is D

18 Installation Notes Examples Loading from UNIX Host To configure a 6800 module to load over link W1, via BOOTP/TFTP, you must map the Ethernet address of link W1 to a 6800 Internet address in the "bootptab" file of the UNIX load host. Similarly, to configure a 6800 module to load over link W1 via RARP/TFTP, you must map the Ethernet address of link W1 to a host name in the load host's "ethers" file. The host name is an arbitrary designation that represents the 6800 link; it is mapped to a 6800 Internet address in the "hosts" file on the load host. Loading from VAX/VMS Host To configure a 6800 module to load over link E1, from a VAX/VMS host, you must add the Ethernet address of link E1 to the NCP and XYP_MANAGER databases on the host. (Chapter 3 of the Software Installation Guide for VMS Kits explains how to configure these databases.) 2.4 Initializing the 6800 Module When you apply power to the Network 9000 chassis, all the modules in the chassis initialize. When you install a module into the chassis, the module initializes. To initialize an installed module, follow these steps: 1. Make a simple "tool" from an ordinary paper clip by bending one end outward. You need this tool to press the module's RESET button. 2. Find the module's reset switch. (Figure 1-1 shows its location.) 3. Use the paper clip tool to press the RESET switch once. The module enters RESET state; all front panel lights go ON. 4. Press the reset switch again. The module performs diagnostic self tests and begins loading the Xyplex Bridge/Router software. This process is described in the following section. After the software load image and parameter files have been loaded, the RUN light should flash once per second, and the repeater port status lights should flash as packets are being received. If the lights do not behave this way, proceed to Chapter 4 "Installation Troubleshooting"

19 Installation Notes Self Test, Software Load Process When you power on the Network 9000 chassis, or initialize the 6800 module, the module performs self tests to verify the operation of its circuitry. Upon successful completion of the self tests, the 6800 module loads Xyplex Bridge/Router software and operational parameters. The RUN light flashes rapidly during the loading process. If the 6800 module is equipped with a memory card, the module will load its software and parameters from the memory card. The CARD light goes on while the memory card is being accessed. Do not remove the memory card, or power off the Network 9000 chassis, while the CARD light is ON. If the 6800 module is not equipped with a memory card, the module will attempt to load software from another 6800 or other Network 9000 processor module, or from a network load host. Loading from another module or a load host typically requires more time than loading from a local memory card. (For information about loading from a network host, refer to Section 2.3). The RUN light flashes slowly -- at 1-second intervals -- after the software has been loaded. If the RUN light does not do this after several minutes, refer to Chapter 4, Installation Troubleshooting. 2.5 Accessing the User Interface (Optional) The following sections explain how to access the bridge/router user interface two ways Using a Directly Connected Terminal Refer to this section if you plan to access the user interface from a terminal or workstation/pc, which is physically connected to the MGMT port on the WAN I/O card. Turn the terminal's power ON. Then, press <RETURN> a few times -- until the 6800 recognizes the device. The 6800 automatically adjusts to the communication speed (75 bps K bps) of a connected terminal that is set up as follows: 8 bits, No Parity -- or -- 7 bits, Even Parity If the 6800 does not respond with a welcome message, press the <BREAK> key, then press <RETURN> a few more times

20 Installation Notes When the module responds, it generates the following message, which appears on your screen: Welcome to the Xyplex Router. Enter username> Type your name, your initials, or a nickname -- whatever you want to be known as while you are connected, then press <RETURN> again. You can type up to 16 characters (numbers or letters); however, do not leave any spaces between the characters. The username is your identifier during this session. You can enter a different username each time you log on to the WAN Processor user interface. The username is shown whenever you or any other person on the network requests information about who is connected to the Bridge/Router user interface. If you are powering up the 6800 for the first time, you will see the following messages. You also see these messages anytime you power up the 6800 with default operational parameters. Xyplex Default Parameters in Use. Do you want to configure this unit (Yes/No)? If you enter 'Y', the bridge/router will run a configuration script. This script is described in Section 2.6. If you enter 'N', the 6800 will return the command prompt: Xyplex> When you see this prompt, the 6800 is ready to accept commands. You can obtain on-screen information about Bridge/Router commands by typing HELP and pressing <RETURN>: Xyplex>HELP Remote (Console Port) Access Refer to this section if you plan to access the 6800 user interface from a remote terminal or workstation/pc, using RCP, Telnet, NETWORK CONSOLE, or CHASSIS CONSOLE. When you connect to the console port of the 6800, you must press <RETURN> until the module responds with the login password prompt. The default prompt is #. Enter the login password at this prompt and press <RETURN>. The default login password is ACCESS. When the module responds, it generates the following message which appears on your screen: Welcome to the Xyplex Router. Enter username>

21 Installation Notes Type your name, your initials, or a nickname -- whatever you want to be known as while you are connected, then press <RETURN> again. You can type up to 16 characters (numbers or letters); however, do not leave any spaces between the characters. The username is your identifier during this session. You can enter a different username each time you log on to the bridge/router user interface. The username is shown whenever you or any other person on the network requests information about who is connected to the bridge/router user interface. If you have powered up the 6800 for the first time, you will see the following messages. You also see these messages anytime you power up the 6800 with default operational parameters. Xyplex Default Parameters in Use. Do you want to configure this unit (Yes/No)? If you enter 'Y', the bridge/router will run a configuration script. This script is described in Section 2.6. If you enter 'N', the bridge/router will return the command prompt: Xyplex> When you see this prompt, the 6800 is ready to accept commands. You can obtain on-screen information about Bridge/Router commands by typing HELP and pressing <RETURN>: Xyplex>HELP 2.6 The Bridge/Router Configuration Script You are prompted to run the configuration script anytime you start up the bridge/router with default operational parameters. In addition, you can start the script anytime by issuing the DEFINE CONFIGURATION command. The script guides you through a basic bridge/router configuration by asking you a series of questions. Configuration settings that you define through the the configuration script take effect immediately. (You do not have to re-initialize the bridge/router for the settings to take effect.) The default values displayed by the configuration script are initial defaults. If you have previously assigned a value for a characteristic, the bridge/router will use the assigned value -- rather than the initial default -- for that characteristic Configuration Worksheets The 6800 module is shipped with configuration worksheets that help you plan your bridge/router setup. Use the worksheets in conjunction with the bridge/router configuration script. After you configure the bridge/router, the worksheets provide a record of how the 6800 is being used in your network. (Make copies of the worksheets that you plan to use, and save the originals.)

22 Chapter 3 Cabling 3.1 Cabling Overview This section describes cabling and signal distribution considerations for the WAN port and the MGMT port of the A serial cable and RJ-12-to-DB-25 adaptor are supplied with each 6800 module. Other serial cabling items are available from Xyplex or other suppliers. Depending on your application, there are different cabling schemes that you can use.

Other serial cabling options available from Xyplex include: 6-wire straight-through cable 7.62 m (25'), male RJ-12 to male RJ-12 (MX ) SYS Adaptor, female RJ-12 to female DB-25 (MX ) DROP Adaptor, female RJ-12 to female DB-25 (MX ) Cabling options available from other suppliers include: SYS Adaptor, female RJ-12 to male DB-25 (MOD-TAP # ) DROP Adaptor, female RJ-12 to male DB-25 (MOD-TAP # ) Standard Xyplex-supplied cabling items enable you to connect to any serial device that uses a male or female DB-25 connector. All that is required is a modular cable and the correct modular adaptor (a male or female DB-25 connector), which is essentially an RJ-12-to-DB25 adaptor. The DROP adaptors are used in 6800-to-DTE (crossover) connections. The SYS adaptors are used for 6800-to-DCE (straight-through) connections. You must consider the wiring scheme when you plan to connect a device such as a terminal or serial printer to the MGMT port. The serial port of the 6800 card is considered a DTE device. To connect the port to another DTE device (such as a VT200 terminal), you need a crossover wiring scheme somewhere in the cabling. (DTE-to-DTE device communication requires a crossover.) To connect the port to a DCE device -- such as a modem -- straight-through wiring is required. In the standard Xyplex-supplied cabling options, signals are directed to the correct pins in the adaptor. (For example, the crossover is made in the DROP adaptor, so that only one type of 6- wire cable is required.) If you make your own cables, you must construct the cable with the appropriate wiring scheme

33 Chapter 4 Installation Troubleshooting 4.1 About this Chapter This chapter explains the steps to take if a 6800 module fails to initialize and load its software successfully. Each section includes a problem statement and suggests possible solutions for the problem. If you need telephone support in resolving a problem, call your Xyplex Customer Support representative. (Inside the U.S. and Canada, call For international calls, the number is ) Modules must be securely seated to ensure proper operation. Make sure that the two front panel screws and two rear panel screws are completely tightened. Problem: The front panel lights on the 6800 module are flashing after power up, or after you re-initialize the module. Indication: The lights are indicating an initialization self-test failure. If the self tests fail, the 6800 status lights will initially flash 8 times very quickly. Then, one or more lights go on. All lights then flash sequentially and additional lights go on. This entire light flashing sequence repeats continuously. Record the numbers of the flashing lights, as shown in Figure 4-1. Note that the light numbers (1 through 8) are not shown on the front panel of the 6800 module; rather the light numbers correspond to lights on the panel

Sample Self Test Failure Indication Possible Solution: If you see an error code, remove the 6800 module and check whether any of the pins are bent in the slot. Then, reseat the card in the slot. It is helpful to back off on the captive screws until they are straight. Slide the card in gently, but firmly. It is best to press the card in the center. Make sure that the card is flush against the other cards and not held back by a misaligned screw. Tighten the screws firmly. If the same failure occurs, call your service representative and report the error code. (In the U.S., call Xyplex Customer Support at For international calls, the number is )

35 Installation Troubleshooting 4.2 Network Software Loading Problems Problem: The 6800 module does not appear to load from a network load server, or is slow to load. Correct Operation: The 6800 module should load within several minutes after power up if it is properly configured at a load server. (The actual time depends on network congestion, host utilization, and similar factors.) The RUN light flashes rapidly after successful completion of the initialization self tests. During the software loading process, the 6800 module sends load status messages to a terminal connected to the MGMT port. You must press <RETURN> continuously -- first to autobaud the terminal speed, and then to receive an updated message with each <RETURN> you enter. If you type <CTRL><T> now, the 6800 module will display the load server offer table when it receives load offers. (You only need to type <CTRL><T> once.) After the software load image and parameter files have been loaded from the load server, the RUN light should flash once per second. Then, if you press <RETURN> several times, the following message should appear on the display: Welcome to the Xyplex Router. Enter username>_ Possible Solutions: If you are loading via Internet protocols such as RARP, BOOTP, and TFTP, these protocols might not be running at the UNIX load server. Refer to the Software Installation Guide for UNIX Load Hosts for information about troubleshooting this problem. Several messages can be displayed by the 6800 module during the load process. These messages might help you resolve the problem. Record the displayed messages and refer to the following descriptions for assistance in correcting the problem. Note that for each time you press <RETURN>, the software displays only one message. You must press <RETURN> continuously -- first to autobaud the terminal speed -- and subsequently to receive an updated message with each <RETURN> you enter. If you type <CTRL><L> following any status message, the 6800 module will generate a WAN link status display, which indicates the transmit/receive clock speeds, cable type, and the status of the DTR, DSR, DCD, RTS, CTS, and RNG signals for each WAN link

36 Installation Troubleshooting Bridge/Router, Type 81, Rev x.xx.xx Ethernet address xx-xx-xx Initializing... A message similar to this one appears for approximately 10 seconds after the self tests complete. (Your addresses will be unique.) If the next message does not appear after you press <RETURN> several times, the 6800 module could be at fault. If you have a spare module available, swap modules. Bridge/Router, Type 81, Rev x.xx.xx Ethernet address xx-xx-xx Requesting network load service A message similar to this one is displayed while the module is waiting for a response to the load request. If this message remains displayed for more than 20 seconds after you press <RETURN> several times, either the 6800 module is not configured on a load server, or the module cannot communicate with a load server. Refer to the Software Installation Guide for the appropriate load server host. Bridge/Router, Type 81, Rev x.xx.xx Ethernet address xx-xx-xx Evaluating service offers A message similar to this one is displayed if the 6800 module has received a load offer from a load server. If you typed <CTRL><T> after the port speed had been selected, the following messages appear: Received load service offers: Host Address protocol merit filename xxx.xxx.xxx.xxx 0800 F000000F xxxxxxx.img One to ten load server addresses are displayed (typically, just one). After the load server has been chosen, the following messages appear: Bridge/Router, Type 81, Rev x.xx.xx Ethernet address xx-xx-xx Loading over Link (Link ID) from server xx-xx-xx-xx-xx-xx, message 0 If the message count remains at zero after you press <RETURN> continuously, the load server was configured to load the 6800 module, but encountered a problem with the load file or directory. Check the file name and directory at the load server. Additionally, at a VAX/VMS installation, the logical name "MOM$LOAD" might not be defined properly

37 Installation Troubleshooting After the 6800 module loads a file, it checks the contents of the file for proper identification and size. One of the following messages can appear if a file problem is encountered: Server xx-xx-xx-xx-xx-xx File error: not a load file. This message type appears if the load server attempted to load a file image that is incompatible with the 6800 module. (The load file did not have a Xyplex ASCII identification string header.) Server xx-xx-xx-xx-xx-xx File error: corrupted data. This message type indicates that the load server attempted to load a file that is compatible with the 6800 module, but the file has been corrupted. Correct this problem by installing a new file in the load server. Refer to the Software Installation Guide that you received with your software for instructions. Server xx-xx-xx-xx-xx-xx File error: not executable. The load file is a Xyplex file, but it cannot be executed by the 6800 module. Resolve this problem by installing the proper file at the load server. Refer to the Software Installation Guide for the appropriate load server host, for instructions. Server xx-xx-xx-xx-xx-xx Timed out, will retry. This message type indicates that the 6800 module has quit waiting for the load server to send a load file image, and restarted the load request process. If the message count was not zero, and the "timed out" message was displayed, it is possible that your network experienced communication problems. Note that if there is no progress of the message count number beyond zero, a server problem probably exists. If the message count remains stuck at a number other than zero, a network problem probably exists. If a failure occurs during the load process, the 6800 module will abort the load process and send a small dump file (approximately 60 bytes) to a server that is configured for a file dump. The dump file can be analyzed by your service representative to assist you in resolving the fault. (In the U.S., call Xyplex Customer Support at For international calls, the number is )
